Lời giải:
a)
\(3x^2-5x+1=2x-3\)
\(\Leftrightarrow 3x^2-5x+1-2x+3=0\)
\(\Leftrightarrow 3x^2-7x+4=0\) (\(a=3; b=-7; c=4)\)
b)
\(\frac{3}{5}x^2-4x-3=3x+\frac{1}{3}\)
\(\Leftrightarrow \frac{3}{5}x^2-4x-3-3x-\frac{1}{3}=0\)
\(\Leftrightarrow \frac{3}{5}x^2-7x-\frac{10}{3}=0(a=\frac{3}{5};b=-7; c=\frac{-10}{3})\)
c)
\(\Leftrightarrow -\sqrt{3}x^2+x-5-\sqrt{3}x-\sqrt{2}=0\)
\(\Leftrightarrow -\sqrt{3}x^2+(1-\sqrt{3})x-(5+\sqrt{2})=0\)
(\(a=-\sqrt{3}; b=1-\sqrt{3}; c=-(5+\sqrt{2}))\)
d)
\(\Leftrightarrow x^2-5(m+1)x+m^2-2=0\)
(\(a=1;b=-5(m+1); c=m^2-2)\)
